RB20DET 148rwkw

[davidl]

Hey Guys,

Had my car dyno on saturday, i made 148rwkw with a stock rb20det with exhaust and FMIC, on stock boost, the guys who dyno the car thought it was way to high so checked out the dyno setup which was correct.

Does this sound right? I have the rb20det in my silvia and didn't bother checking the turbo before it was on. Do you think it is a stock turbo?

yeh this sounds right.

standard they are suppose to come with 210ps so it does equal around what you have got. next get the turbo and computer done.

my cuz did the same mods as you and the turbo/computur pulled 200rwkw.

most things i've read on mods to the r32 rb20det say that with the mods you have and also a rechipped ECU running 14psi should get around the 160rwkw mark?? are you shaw it was kws not hp as thats about the same reading?? i've been told that a vg30 turbo could get that kind of result but also with higher psi and tuning???

210-215ps is around 160kw AT the Flywheel. Not rear wheels.

148rwkw (~200-210kw at the FLYwheel) with say 11-12psi (which is where it should be with an Exhaust) is around the mark.

With AFR's at 12:1 & a few more degree's of ignition timing mine made 152rwkw on 12psi. I would say your AFR's are not rich, which is bad as when you decide to pump more boost in the old fuel pump won't want to come to the party and you will lean out.

15psi only saw a 12rwkw increase as the turbo begins to heat the air more and runs out of efficiency.

With a tuned computer 170rwkw is around the maximum you will get.

200rwkw must have been a very optimistic high reading dyno. Most probably a Hub Dyno.

The RB20DET in my GTS4, with 3" cat-back, T3/T4 hybrid turbo running around 10psi, and FMIC, punted 145rwkW.

Was she running as rich as hell?

[GTSR22]

na man this car was as quick as my dads old race car and that just pulled a 2:22 around bathurst.

it is also the way you tune your computer to get the big hp

cya guys

Mine got 142.8rwkw, 12psi, and just the stock cooler. So I guess its pretty much on the money.

[Cubes]

A turbo can only flow so many cfm's before it starts chopping and superheating the air.

What dyno was that 200rwkw pulled on? All bets are it wasn't ran in the correct shootout mode/temp sensor placed incorrectly or it was on a hub dyno.

Doesn't matter, Dyno's are only good as a base tuning tool.

Shootout mode tries to make it an even playing field.

my friend got a similar result with similar mods

so i think its accurate

My mates VL has an RB20 with a GTR cooler, stock turbo, 3 inch cat back, 14psi he got 148rwkw.

[RBsileighty]

148rwkw... are you running a converter? A buddy of mine had his on the rollers and put down 230rwhp (~171rwkw) with the same mods... but no converter.

I'm ready to get mine on the rollers and see how this T3/T4 will do once it's rebuilt.

My RB20 did 137 rwkw with turbo back exhaust, pod and R33 turbo on stock boost and everything else stock. A/F ratio was 13 and it had a slight misfire.

After upgrading the fuel system it went down to 130 rwkw and a healthy 11.3 fuel ratio and no misfire.

This was on DynoDynamics dyno in shootout mode at Unigroup.

i got 140rwkw on stock rb20det with standard turbo and cooler running 12psi.........

[Mr GTS4]

i got 138rwkw in my GTS-4 with turbo back exhaust, filter, stock cooler and turbo 13psi, 80% blocked radiator ( fixed now ), on a 38 degree day.

[VLRB20DET]

i got 120rwkw on stock boost, fmic, pod filter and 3" zorst and was running 3.45 (VL) diff gears

I think it would be around 140+rwkw now, 14psi boost and 20 deg timing

I just fitted a wolf 3d along with a front mount, pump, full exhaust etc and rolled 152rwkw on a roller. I've had it on a hub a few times and the numbers are CONSIDERABLY higher. Without the dump it was showing 176 rwkws (yeah.. right). Car is heaps faster on the road. Just looking at turbo upgrades now.... I'd like a real 200 - 210 rwkws.

Off topic but hey. How are you finding the wolf 3D? Is it the V4 and did you get the plug and play version?
